Configuration Menu Functions
Configuration Menu
The projector is equipped with a power-saving function that causes the power to turn off automatically
and the projector to switch to standby if no signal is input to the projector for a continuous length of time.
The length of time before the power-saving function operates can be selected from four available
settings. If OFF is selected, the power-saving function will not operate.
If you press   while the projector is in standby mode, projection will start again.
This locks the power on function of the   button on the projectors control panel, so that a child cannot
accidentally turn the projectors power on and look into the projectors lens.
When the lock is applied, the power will only turn on if   is pressed down for about 3 seconds.   can
be used to turn off the power, and the remote control will continue to operate as normal.
The remote control operation is unaffected by this setting.
If you change the setting, the new setting will take effect after the power has been turned off and the
cool-down period is complete.
A fan is set at a certain speed of rotation so as to bring down internal temperature.
When using above an altitude of about 1500m, set to ON.
You can record your favorite image as a users logo.
The logo will be projected when projection starts and when the A/V mute is set. When a users logo is
recorded, the previous users logo will be erased. Follow the instructions on the screen to record a user ’s
logo.
•The image will be displayed in dot format while the selection frame is displayed, therefore the display
